Shenhai e fakamoʻoni fakaʻauha
ʻOku fie maʻu ʻe he faʻahinga meʻangaue fakaʻuhila kehekehe ʻa e ngaahi tuʻunga maluʻi kehekehe. Ko e ngaahi tuʻunga moʻui ko ʻ, ʻiloa ko e maaka maluʻi, denote the casing’s capability to block external objects from penetrating its interior and to provide resistance against water ingress. Fakatatau ki he “Ngaahi tuʻunga ʻo e maluʻi ʻoku ʻomi ʻe he ngaahi puha (Kouti IP)” (GB4208), a casing’s protection grade is denoted by the IP code. This code comprises the initials IP (International Protection), followed by two numerals and sometimes optional additional letters (which are occasionally omitted).

The first numeral indicates the degree of protection against solid objects, while the second numeral represents the water resistance level. Protection against solid objects ranges across 6 tuʻunga: tuʻunga 0 signifies no protection, and level 6 indicates complete dust-tightness, with protection increasing progressively from 0 ki he 6. Ko e meʻa tatau pe, water protection spans 8 tuʻunga: tuʻunga 0 denotes no protection, and level 8 indicates suitability for prolonged submersion, with protection increasing progressively from 0 ki he 8.
